武鸣县人体肠道寄生虫病监测结果分析

Analysis of the Results of Surveillance on Intestinal Parasites in Wuming County

目的了解武鸣县肠道寄生虫感染现状,为今后的防治工作提供可靠依据。方法收集本单位历年人群粪便检查等疫情资料进行汇总分类和分析。粪便检查方法采用改良加藤法和醚醛法。结果 1990-1995年查出肠道寄生虫13种,感染率为61.93%,其中线虫感染率为42.37%,吸虫感染率为28.38%。1996-2000年线虫感染率下降至20.32%,吸虫感染率上升至32.12%。2001-2008年查出7种虫种,线虫感染率降至4.81%,吸虫感染率上升至44.00%。结论肠道寄生虫感染虫种大幅下降,部分线虫、原虫感染率已控制在较低水平,肝吸虫感染率逐年上升,已成为主要感染虫种,应加强防控工作。

Objective To understand the infection status of the intestinal parasites in Wuming County for future control activities.Method Collection and analysis were performed on the stool examination data which were done with modified Kato Kaz and formalin ether sedimentation technique in previous years in the residents of Wuming County.Results In 1990-1995,totally 13 species of intestinal parasites were found and the overall infection rate was 61.93%.Among of them the infection rate of intestinal nematode was 42.37% and the trematode was 28.38%.In 1996-2000,the infection rate of intestinal nematode decreased to 20.32%,and that of trematode increased to 32.12%.In 2001-2008 only 7 species of parasite were recorded and the prevalence of nematode kept going down to 4.81%,but that of trematode increased to 44.00%.Conclusions The species of intestinal parasites reduced significantly in past two decades.Nematode and protozoon infection were controlled to low prevalence level.However,the prevalence of liver fluke is rising sharply and became major parasite in the county.Liver fluke control activity should be considered as top priority in this area.
